Performance Difference Between 4 Speed And 6 Speed Auto's?

[our06t]

ha ha not you I was replying to the post above you

but if you look in time slips he has his 10.88 run and the 376rwkw graph next to it but that was on micky t 's

I understand that the tuning will differ for each respected gearbox, but if one car is tuned for boost to come on hard, early and the other is tuned where boost comes on progressively??...

I dunno... Maybe mph is a good indicator.

Good idea

Maybe a new thread is in order...

sounds good

Was that 376rwkw on a hub or roller dyno? Do you remeber mph for the run??

Sorry for the questions but I hate the search button

[our06t]

124 mph so less than the zf

that's why I don't think the mph should come into it the mph doesn't win the 1/4 the time does ,

so looking at just those 2 power and times looks like the 4spd is quicker early on but holds out towards the end probably because of holding 3rd gear till the end

and timeslips is a sect at the top of the page don't have to search for them

4 speeds are definitely quicker as it stands judging by that time/mph but has it been backed up yet? More results are needed to see a consistent trend imo.

[our06t]

that's what I'm interested in not enough dyno prints to go with the times in timeslips sect

[Guest]

Dyno graphs aren't really a fair comparison though. Each dyno differs pretty significantly, hence the mph should be used as the main indicator

[our06t]

yeah it only gives an idea

so how would that work

example car does 11.1 at 124 the other 11.2 at 126 does this mean the second car has more power but is slower on the 1/4 ?

I know there are many variable's in this driver tyres on an on anon

just thought we might be able to get an average idea

That's why a large sample space is required. It weeds out the irregularities such as you have listed.
